A fortnight ago, we reviewed the two latest electric bikes now on sale at Cambridge's Electric Transport Shop – the Haibike XDuro NDuro RX 2015 and the Bergamont E-Ville A8. The electric bike specialists, who also have outposts in London, York, Oxford and Bristol, are now celebrating the revamp of their website and online shop by offering promotions on selected bikes.

The store will feature on BBC2's 'Inside the Factory' next week at 8pm on Tuesday, with an edition called 'Bicycles.' The TV programme sees Gregg Wallace and Cherry Healey tour factories around the UK to find out how products are manufactured.

For next week's bicycles edition, Cherry Healey visits Cambridge to speak to industry insiders about the 'Future Bike.' Part of the edition is filmed outside King's College, where they asked people to ride different bikes and give feed feedback.

Greg Wallace explores the largest bicycle factory in Britain, which manufactures 150 folding bicycles in 24 hours, and even tries his hand at making a bike. He also goes to a leather saddle maker in Birmingham that was founded 150 years ago, learning that the use cowhide from cows in the UK and Ireland because the cold weather causes them to have thicker skins.

The Haibike retails at the Electric Transport Shop for £4,600, but the Bergamont, which normally sells for £2,600, is currently on sale at £2,000. Additionally, the high tech bike shop is the first retailer to get details of the 2017 edition.

The store will have a special offer for pre-orders of the 2017 Haibike range once full details are released.

The store also has the Wisper 2017 range in stock now, which come in different colours including dark red and light blue, retailing from £999. The Wisper range includes disc brakes, a Japanese Dapu motor and controller, and an LCD display.

“The bike that stops most people walking past the window is the retro Raleigh Chopper, brought bang up to date with a futuristic drive system fitted," says Eddie Kehoe, store manager of the Cambridge Electric Transport Shop. The bike was originally manufactured in the 1970s by the Raleigh Bicycle Company in Nottingham. For at least one generation it was a must-have bike and cyclists in the UK have such fond memories of it so the shop decided to build a custom model for today's market.

The Electric Transport Shop is located on 118-120, Newmarket Road, CB5 8HE. The shop is open from 10am to 5pm, Tuesday to Saturday.
